Journal ArticleDOI
Polishing-induced contamination of fused silica optics and laser induced damage density at 351 nm.
TL;DR: It is shown, owing to recent developments of raster scan metrology, that a good correlation exists between damage density and concentration of certain contaminants for the considered parts.
Journal ArticleDOI
Discrete element method to simulate continuous material by using the cohesive beam model
TL;DR: The aim of the present work is to improve the ability of DEM to simulate the continuous part of the material using cohesive bond model, and simulates, using a discrete element model, any material defined by a Young's modulus, Poisson's ratio and density, to fit the static and dynamic mechanical behavior of thematerial.
Journal ArticleDOI
Diffraction gratings: from principles to applications in high-intensity lasers
Nicolas Bonod,Jérôme Néauport +1 more
TL;DR: In this article, the authors review the physics of diffraction gratings and detail the interest in them for pulse compression of high-power laser systems, showing that the unique spectral properties of these gratings revolutionized the field of high energy laser systems.
Journal ArticleDOI
Effect of electric field on laser induced damage threshold of multilayer dielectric gratings
Jérôme Néauport,Eric Lavastre,Gérard Razé,Gabriel Dupuy,Nicolas Bonod,M. Balas,G. de Villele,Jean Flamand,S. Kaladgew,F. Desserouer +9 more
TL;DR: This paper studies gratings engraved in multilayer dielectric stacks for ultra high intensity laser compressors application and evidenced that for fixed incident angle and materials the damage of the grating is directly related to the electric field intensity maximum in the material, which depends on the groove profile.
Journal ArticleDOI
Using the discrete element method to simulate brittle fracture in the indentation of a silica glass with a blunt indenter
TL;DR: In this paper, the authors used a discrete element model based on interaction given by 3D beam model to simulate the elastic properties at the macroscopic scale of brittle cracks, which is achieved by computing a failure criterion based on an equivalent hydrostatic stress.
